Abstract

We have designed and grown triply doped LiNbO3:Zr,Cu,Ce crystal and investigated its characteristics of nonvolatile holographic storage. It’s observed that the photorefractive sensitivity of LiNbO3:Zr,Cu,Ce has improved to 0.099 cm/J, which is about one order of magnitude larger than that of congruent LiNbO3:Cu,Ce. And LiNbO3:Zr,Cu,Ce also has high suppression to light-induced scattering. Our results indicated that triply doped LiNbO3:Zr,Cu,Ce is an excellent candidate for nonvolatile holographic data storage.
